Infiitely many.
Start with integers and addition/subtraction:
6+5, 7+4, 8+3, 9+2, 10+1, 11+0, 12-1, 13-2, ...
Then with one decimal place:
5.5+5.5, 5.6+5.4, 5.7+5.3, and so on.
Then with 2 dp, 3 dp, and so on to infiitely many dp.
Next look at multiplication/division.
1*11, 2*5.5, 3*3.66..., 4*2.75, and so on
Then there are other ways of combining numbers, such as exponentiation and so on. But the solar system will have ended before you get there!
Infiitely many.

Not counting negative numbers (which would give you an infinite number of ways of adding numbers together to equal 10), there are 6 different ways (permutations) of adding numbers together to equal 10. 0 + 10 1 + 9 2 + 8 3 + 7 4 + 6 5 + 5
4p3*3p1 equal to 72 ways
One... numbers
24 ways
what equals 117
30

25 and 5 but there are more ways that equal to 125
4p3*3p1 equal to 72 ways
14? There are 35 ways to combine 5 objects from 7 1 way from 5 6 ways from 6 70 from 8 126 ways from 9 for more info , google "Pascal's Triangle"
25 ways. 25 ways. 25 ways. 25 ways.
Ignoring the order of the primes, there is only one way.
You can combine variables in many ways with normal numbers, or with other variables, for example, x/3, 1/x, x/y, (1+x)/y, etc.
With whole numbers, there are five ways.
One time, because all prime numbers are odd numbers, and the only numbers that go into it are 1 and itself. Therefore there cannot be any number of rows with the equal number of coins. Just one row
One... numbers
many ways i think like 50
